SPECIFICATION forming part of Letters Patent No. 375,799, dated January 3, 1888i i Application filed October 2l, 1887. Serial No. 252,940. (No model.) I

To @ZZ whom it may concern:

Be it known that I, MARTIN BYE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in -connection with the drawings making a part lo of this specification, will enable others skilled in the art to which my inventionfbelongs to make and use the same.

My invention relates to improvements in fire-arms, and `more particularly to mechanism for locking the hammer to prevent the accidental or inadvertent discharge off'ithe re arm; and my invention consists in certain novel features of construction and operation ofthe locking mechanism and parts connected 2a therewith, as will be hereinafter fully described, and the -nature thereof indicated by the claims.

Referring tothe drawings, Figure 1` is a side elevation, partly in section, of a revolver embodying my improvements.

parts ofthe cooking and tiring mechanism are shown in their normal position with the hammer locked. Fig. 2 corresponds with Fig. 1,v except that the hammer is Shown unlocked 3o and partially cocked and the trigger and parts connected therewith partially operated preparatory to discharging the revolver; and Fig. 3 is a detached Section of the revolver to illustrate' how the hammer is automatically unlocked when the barrel-catch is drawn back to allow of the barrel being tilted on the stock for the discharging or refilling of the cartridgecylinder.

In the accompanying drawings,` the barrel 4o lis connected by a hinge-joint at 2 with the stock or handle 3, and is adapted to be tilted thereon in the ordinary manner. A revolving cartridgecylinder, 4, is supported and turns on its'central stern secured in the barrel portion in any well-known manner.

The cooking and firing mechanism shown is of the ordinary constructionin thisvclass of revolvers,'consisting of the trigger 5, pivoted in the stock, and an actuating-spring, 6, a pawl,

5o 7, for revolving the cylinder, and a Sear, 8,

The several for cooking the hammer, both pivoted on the trigger 5in the ordinary manner, and a spring,

' 8. Said spring 9 serves to keep .the pawl 7 in- 55 vengagement with the ratchet-teeth on the rear end of the cylinder 4, and also to keep the upper end of the senr 8 in contact with the hammer l1..

E In the present instance Sear 8 provided with a'n adjusting screw, 12, extending through the lower end thereof, with its inner end adapted to bear against the triglv ger in the process of cooking the hammer.

(See Fig. 2.) The object of this is to provi'de 65 for any 'wear or abrasion of the inner upper edge of the Sear 8, and to cause the'same to fit against and operate the hammer in the proper manner, notwithstanding anywearor abrasion of the Sear. adjusting screw, 13, extending through the un der side of the stock or handle 3, with its inner end adapted to bear against the lower end o f the scar 8 whemthe parts of the tiringimechanism are in their normal positions, (see Fig. 7 5v 1,) for the purpose of holding the sear up in contact with the hammer at its upper'end and provide for any wear or abrasion of the upper end of the Sear, and also to prevent any looseness or rattling of the scar or trigger.

The 'hammer 11 is hung in the stock or handle on a pin, 14, and is provided with a notch or projection, 15, with which the sear 8 engages in the usual man ner. A mainspring, 16, is connected with the hammer 11 in the ordinary manner, and the upper end of the hammer is `adapted to strike against the firingpin 17 of ordinary construction. f/

In the upper part of the stock is pivoted, on a pin, 18, in front of the hammer 11, the barrel-catch 19, which is cut out upon its interior surface to permitI of the upper end of the hammerll freely moving back and forth A hole, 20, is made in the within the same.

uforward'part of the catch 19, through which 93.

the iringpin174 extends. Thepupper end of the catch 19 is provided with a projection or lip, 21, adapted to engage with a corresponding notch, 22, in the end of the barrel portion to hold the barrel I have show-n the 6o I have also provided an' 7o down upon thestock. A roo:

spring, 23, forked at its upper end, is secured within the stock or. handle and presses at its upper end against the lower end of the catch 19, and serves to keep the same up in its proper through a hole, 26, in the upper side ofthe.v

handle, just at the rear of the barrel-catch, and its inner end adapted to engage with the hammer l1 and lock the same when the outer end ofthe ck1ever 25 is tilted up,I (see Figs. 1 and 3,) and to extend above the hammer and `a1low the free cooking thereof when the outer end of the lock-lever is tilted down. Fig. 2.)

The lock-lever 25 is so constructed and hung in the stock or handle 3 that when its outer end is drawn down so as to tilt up its inner end, as indicated in Fig. 2, it will not engage with the hammer 1l to lock the same, but will allow it to be freely'cocked; but when the outer end of the1ook-lever 25 is pushed up, as indicated in Fig. 1, the inner end ofsaid level' will be tilted down to engage the hammer and preventitfrom being cocked. The lock-lever 25 is hung in the stock or handle 3 in such a manner as to extend into the line or path of movement of the barrel-catch19, so that when (See the barretcatoh 19 is drawn back to release the barrel portion and allow it to be tiltedon v the stock, as indicated in Fig. 3, thelower end of said catch 19 will bear against the lock-lever 25' outside of the'pivot-point in such a manner as to tilt up theinner end of the locklever and unlock the hammer, so'that when the `barrel and stock are brought together again the hammer will, be unlocked and the revolverready to be discharged. By' pressing u p the outer end of the lock-lever 25 the hammer may be securely locked and the ro v olver prevented from discharging.

It will thus be seen from the above descrip# tion, in connection with the drawings,that by means of the lock-lever 25, pivoted withinlthe handle and with its outer end extending through the upper side ofthe handle where it can be easily operated by the thumb of the operator, I have provided a very simple and effective means for the locking and unlocking of the hammer of the revolver, and, further, that by means of said lock-lever 25 extending into the path of movement of the bar reLcatch 19, in connection with said barrel-catch 19, I have provided for the automatic unlocking of the hammer every time the barrel-catch is drawn back to release the barrel portion and allow it to be. tilted on the stock.

My improvements may equally well be applied to other kind of fire-arms, and I do not limit myself to their use in revolvers.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fire arm, a hammer-locking lever' pivoted in the upper part of the handle, with its inner end adapted to engage the hammer to look the same and its outer end extending through the handle and into the path of move'- ment of the barrelcatch, for the purpose stated, substantially as shown and described.

2. In a fire-arm', the combination, with the barrel-catch hung in the upper part of the handle, of a hammer-looking lever pivoted within the handle, with its inner ond adapted to engage the hammer to lock the same and its outer end extending into the path of movement of the barrel-catch to be engaged thereby to unlock the hammer, in the manner substantially as shown and described.

3. In a fire-arm, the combination, with the barrel-catch hung in the upper part of the handle at a point in front of the hammer and out out upon its inner surface to allow ofthe hammer moving freely back and forth within said catch, andl said hammer hung within the handle,. of a hammer-lockingl lever pivoted within the handle, with itsl inner end adapted to engage and lock the hammer and its outer end extending into the path of movement of the barrel-catch, for the purpose stated, sub- -stantially as set forth. 4

4. In a firearm, the combination, with a sear for cooking the hammer, provided with an adjusting-screw extending through the lower end thereof to engage the trigger, of an adjusting screw secured in the stock or handle to bear at its inner end against the lower end ot' said sear, for the purpose stated, substantially as shown and described.

5. In a re arm, the combination, willi the sear for cooking the hammer, of an adjustingscrew secured in the stock or handle and adapted to bear at its inner end against the lower end of said sear, for the purpose stated,

substantially as shown and described.
